A pH probe left dry between uses loses accuracy fast, and once a probe dries out, response times slow down and readings drift. Bluelab pH Probe KCl Storage Solution solves this by keeping your pH probe or waterproof pH pen properly hydrated whenever it's not in use, protecting its accuracy and extending its working life.
Simply store your probe tip in the KCl solution between measurements to keep it in ready-to-use condition. It's suited to any Bluelab pH probe or replaceable probe pen, making it an easy addition to routine maintenance for growers running one meter or managing a full commercial fleet.
Sold exclusively in box-of-6 case packs, available in 120ml (4.06fl.oz.) or 250ml (8.4fl.oz.) bottle sizes — choose the size that matches your usage and restocking needs from the size selector.
